The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.6 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.6 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00013 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

SINOPSIS

Smoke-wire visualizations and hot-wire measurements are employed to investigate the acoustically excited impinging plane jet with a small cylinder, which is located in the jet potential core region. The jet exit velocity is from 2 to 20 m/s, with the Reynolds number being from 2.1 × 103 to 2.1 × 104 based on the initial jet width. The impinging jet is locally excited at the nozzle exit of the jet flow by two arrays of small loudspeakers at various frequencies. In succession to our previous works, in this study, combined impingement and acoustic excitation reveal the competition of instability waves between the jet and the cylinder wake in the near field of the jet flow. The smoke-wire visualization provides clear qualitative interaction flow behaviors from the instantaneous flow pictures taken at different times. While in the quantitative analysis, the cross hot-wire anemometers in velocity measurements specifically present the detailed physical flow properties. Comparison of the relevant results obtained by these two methods is extensively studied in the paper.
